Barack Obama on the Tube

This teaser campaign on the Tube is driving loads of people mad. Jake Stride spotted the following poster at Bank London Underground station and wondered what it was for:


"Barack outside number 10. No company brand or anything, what's it about?"

Suw Charman over at Flickr has been having the same discussion and you might have seen some of the other pictures in the apparently random set - including a golden football, a chubby kid in swimming trunks, a woman doing yoga (pictured below), the CERN Large Hadron Collider and David Cameron walking past a statue of Winston Churchill.


I wonder the same. I'm sure there'll be some follow up in a few days time, otherwise it's all very puzzling, yet as a teaser campaign it's certainly ... errr .. teasing.

If you've any idea how they are all linked put us out of our misery. Please!
